Thanks so much for the response.

I actually did enable extended
logging with all options yesterday, figuring maybe it would be a good
idea. However, not being an expert at SMTP log files, I don't see
anything suspicious (I'm looking for information on looking at log
files, but most of it is about web log files, not SMTP). It just
looks as if it's "doing it's thing." I also tried your suggestion of
turning SMTP off and back on again. I thought maybe if I put a test
message in the Pickup folder and then turned it back on, the message
would "magically" get sent. No such luck.
Here's something else that's very very strange. This morning, for the
first time, I got mail from this SMTP server, but only in the form of
a warning notification. This was from a test message I sent to myself
from myself yesterday (I've changed the email addresses here):
to:myaddress@theoffice.com
from:myotheraddress@thesameoffice.com
subject:This is a test.
this is a test.
okay?
So, after a day, I got 5 notices at myotheraddress.DeleteThis@thesameoffice.com
like this:
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
myaddress.DeleteThis@theoffice.com
!!!!???? If it could send send the warning message to my address at
the office, why could it not send the message to my address at the
same office?! (It also has been unable to send to
myotheraddress.DeleteThis@thesameoffice.com except for this warning message.)
So, only warning/failure messages can get sent. Bizarre!
Anyhow, here's part of the SMTP log (I've changed some of the IP
addresses and other names). I'd be interested if you can make heads
or tails about what's wrong from this:
